Casey Kasem, the iconic radio host and voice actor, passed away Sunday at the age of 82.

For a certain generation, Kasem was the inimitably raspy voice of the American Top 40 countdown. However, Kasem had a long career as an actor, particularly as a voice actor. Here are seven memorable characters you may not have realized that Kasem was behind.

Norville "Shaggy" Rogers, Scooby-Doo

Kasem voiced Norville "Shaggy" Rogers from 1969-1997 and again from 2002-2009. A strict vegetarian, Kasem suggested that Rogers be one on the show as well.

Robin, SuperFriends

One of Kasem's first voice-acting roles was Robin in The Batman/Superman Hour in 1968. He continued to voice the Boy Wonder through various iterations of the SuperFriends franchise and continued voicing the character until 1985.

Alexander Cabot II, Josie and the Puysscats

Kasem provided the voice of Alexander Cabot II, the Pussycats' less-than-scrupulous manager, for two runs of Josie and the Pussycats (the original series in 1970 and the "reboot," 1972's Josie and the Pussycats in Outer Space). In 1973, Kasem was left talking to himself, quite literally, when Cabot and Shaggy appeared in a Josie-guested episode of The New Scooby-Doo Movies.

Peter Cottontail, Here Comes Peter Cottontail

Kasem starred as Peter Cottontail in the 1971 Rankin/Bass special. Fun fact: Kasem's nemesis in this film was Vincent Price, who voiced "January Q. Irontail," surely the most terrifying rabbit in all of cinema.

Various Transformers, Transformers

In both Transformers: The Movie and the animated television series that ran from 1984 to 1987, Kasem gave voice to Cliffjumper – he also voiced Bluestreak and Teletraan I.

Mark, Battle of the Planets

Kasem, apparently determined to corner the market on '80s animation, provided the voice for Mark, one of the five young people making up G-Force, the leads of Battle of the Planets, an American adaptation of the Japanese show Science Ninja Team Gatchaman. (Good choice on the name change.)

Various Characters, Sesame Street

Kasem voiced several characters for Sesame Street, notably the Blue man in the 'Q for Quarter' Cartoon, from 1971-1990.
